Abstract We present an approach for learning to translate an image from a source domain X to a target domain Y in the absence of paired examples. 1. Introduction Paired training data (left) consists of training examples {xi , yi} N i=1, where the correspondence between xi and yi exists . unpaired training data (right), consisting of a source set {xi} N i=1 (xi ∈ X) and a target set {yj}M j=1 (yj..
